I feel like I'm talking to myself here In case someone else has the same problem: I can reboot with sd card installed and the system recognizes it. I googled the problem and someone posted a wordaround:# sudo echo 1 > /sys/bus/pci/rescanDidn't work but the reboot does.

And after you reboot, do you have write access to the memory card? Or just read only?I can't get myself to mount the SD card with read-write permissions.I'm currently using the latest kernel edition (3.11.3) on AMD64.Any ideas even on how to debug the problem?

My card reader mysteriously started to work complete with read/write permissions. The only thing I did was Settings->Desktop and turn on "Show Mounted Volumes". Turned it off later and it still worked so doubt that was the solution. I have 2 laptops running LMDE and both card readers now work.It's a known bug in Debian and you can get a lot of info by searching the Debian forum. I also read that some have luck using gparted to find the sdcard.Good Luck...
